Vertical Scaling in AWS! 📈✨ Boost performance by increasing power on existing instances. Ideal for applications needing more resources on a single machine. Easy with cloud services like Amazon EC2. 🚀💡 #AWSscaling #VerticalScaling #HorizontalScaling #AWS

Understanding Horizontal Scalability in AWS! 🔄✨ It means adding more instances/systems, especially useful for spreading things out. It's a common practice in websites and modern apps, making it easier to handle increased demands. 🚀💡

It's noteworthy that REST and GraphQL can work together. Since GraphQL doesn't dictate a specific application architecture, it can be introduced on top of an existing REST API and can seamlessly integrate with existing API management tools.

In REST, multiple requests are often needed for related data. In contrast, GraphQL retrieves all data in one request via a simple schema-following query, avoiding over-fetching.

🔗 GraphQL vs RESTful API 📌 REST is talkative, sharing everything it knows, whether you're interested or not. GraphQL, however, is more reserved—offering only necessary information but ready to provide more upon request. #API #GraphQL #RESTfulAPI

AWS Cloud Development Kit (CDK) – offers a revolutionary way to define cloud infrastructure using familiar programming languages like JavaScript, TypeScript, Python, Java, and .NET. Unlike traditional CloudFormation. 🚀 #CloudDevelopment #AWS

In Continuous Delivery (CD), code, after passing tests in Continuous Integration, is automatically deployed. The CD process deploys it to various environments, ensuring constant readiness for release and enabling frequent, reliable deployments.

In software development, developers submit code to GitHub or CodeCommit. In the CI (Continuous Integration) process, a testing server, like CodeBuild or Jenkins CI, quickly checks for issues, enabling rapid bug fixing and accelerating code delivery.

I have always found CI/CD a little bit complicated, but here's my personal simplified explanation of what CI/CD is and what it does at a high level. #CI #CD #CodeCommit #Automation #ContinuousIntegration #ContinuousDelivery #TechExplanation 👇
